A Center of Excellence for R&D in coconut and coconut based farming systems


The  programs of PCA-DRC are both regional and national in scope. Its mission is to generate appropriate technologies on farm-based problems in crop agronomy, farming systems and integrated pest management with the end-view of increasing farm productivity and income.


  • To generate appropriate and sustainable technologies on cultural management, intercropping, integrated soil fertility management and product and by-product utilization in coconut;
  • To generate practical, environment-friendly and sustainable pest and disease management schemes in coconut farming;
  • To strengthen research-extension interface and institutional linkages for sustainable agro-technology utilization; and
  • To provide research information and enhance utilization of mature technologies by target clienteles

Technical Divisions

  • Agronomy, Soils and Farming Systems – conducts researches on agronomy, nutrition and farming systems with the goal of increasing productivity and profitability of coconut farms
  • Integrated Crop Protection – identifies pest and disease problems affecting coconut industry, thereby formulating practical, sustainable, environment-friendly and socio-economically acceptable control measures.


  • Mini Soils Laboratory
  • Leaf Sample Preparation Laboratory
  • Embryo Culture Laboratory
  • Trichoderma Mass Production Laboratory
  • Entomology Laboratories
  • Pathology Laboratories
  • Experimental fields and screenhouses
  • Agro-meteorological Station
  • ICT Facilities and Library


R&D Breakthroughs

Agronomy, Nutrition and Farming Systems

  • Mapped out the nutritional deficiencies of coconut areas
  • Established nutrient critical levels and developed a fertilizer recommendation software
  • Discovered the essentiality of chloride ion in coconut nutrition using the common table salt.
  • Established the nutrient requirements of palms from seedling to full bearing vIdentified effective inorganic and organic fertilizers for coconut and intercrops.
  • Developed feasible productivity and profitability-enhancing coconut-based farming systems technologies
  • Production of natural and nutritious coconut toddy or sap-based food products (cocosap drink, coco concentrate, sugar and vinegar).
  • Sequential coconut toddy and nut production scheme (SCTNP)
  • Production of cocopeat-based bioorganic fertilizer, vermicompost and microbial inoculant.
  • Developed the coconut leaf pruning (CLP) technique or the removal of lower leaves for better sunlight management
  • Developed a technique in estimating nut and copra yield of palms vFormulated a multinutrient inorganic fertilizer grade (14-5-20% NPK with 0.2%B, 15.5%Cl and 4.5%S) found effective not only for coconut but also for intercrops

Integrated Pest Management

  • Formulated an Integrated Pest Management Strategies for the coconut rhinoceros beetle: (i) Discovered the efficacy of trap box containing sawdust incorporated with green muscardine fungus in preventing beetle outbreak in newly felled coconut situation by trapping the initial wild beetle population; (ii) The Metarhizium anisopliae or the green muscardine fungus (GMF) was found effective in controlling beetle population by: a) incorporating the granular form of this entomopathogen into trap boxes, b) injecting or pouring its spore suspension using a spray gun (sumpit) into the beetles’ breeding places, and c) introducing GMF-inoculated larvae of the beetle into trap boxes and breeding areas;
  • Integrated Pest Management strategies for the coconut slug caterpillars: (i)Discovered the use of ultra violet light trap installed in the field at night time resulted to more catches of adult moth of slug caterpillars and proven as one of the effective control measures (ii) Successfully mass reared a predatory pentatomid bug, Eocanthecona furcellata and designed technique for effective release against the slug caterpillar
  • Identified new mite species, Rarosiella cocosae that caused outbreaks in the island of Camiguin, and an introduced mealybug species, Nipaecoccus nipae infesting mature coconuts and banana intercrops
  • Developed rearing technique for the imported tachinid fly, Argyrophylax basifulva Bezzi, a larval-pupal parasitoid of the coconut spikemoth.
  • Designed a “Drill Pour Plug” (DPP) Method that makes use of the fumigant action of the insecticides to prevent further damage by the Asiatic palm weevil.
  • Discovered and identified a potential parasitoid, Tetrastichus sp. attacking pupae of the Brontispa longissima, and developed rearing technique for mass production and field release.
  • Successfully mass produced gall fly, as biological control agent against Chromolaena odorata (Hagonoy weed)
